Title: An improved method of regulating the temperature of a room or space heated by a heating plant having a large thermal capacity
IPC: G05D23/275
Filed: 1937-08-04
Abstract: 488,139. Electric control systems. LANDIS & GYR AKT.-GES. Aug. 4, 1937, No. 21470. Convention date, Dec. 4, 1936. [Class 40 (i)] [Also in Group XXXV] In a space heating system in which the heating is intermittent under the control of a regulator according to the temperature external to said space, a thermostat subject to the space temperature is arranged to permit continuous action of the heating plant until the desired temperature is reached whereupon normal control by the external regulator commences. Excessive temperature of the space causes the thermostat to modify the action of the external regulator to extend the periods during which heating is suspended. A room thermostat 12 engages a contact 13 until the desired temperature is reached thus energizing a relay 15 to de-energize the heating element 19 of the regulator 21 subject to external temperature and prevent operation thereof. Heat control apparatus, such as a motor 27 driving a fan of a coal fired heating plant, thus remains in continuous operation. When the contact 13 is disengaged a transformer 16 is energized through a contact 24 operated by the regulator and intermittent operation of the fan results since the fan switch 26 is mechanically coupled to the regulator 21 (a bimetallic strip for example). When the room temperature becomes excessive a contact 14 is made and the transformer is energized through a resistance 18 shunting the contact 24 to maintain sufficient current in the heating element 19 to prolong the periods of interruption of the fan motor circuit. The thermostat 20 may be operated by the temperature of the heating fluid to hold the switch 24 open when this fluid becomes too hot. Similar control of a damper motor by the invention is also described. Specification 472,087 is referred to.

A coupling for two conductors which are nominally co-linear but which may not be truly in alignment comprises a metal sleeve 20 slotted from each end to form resilient fingers 23, the free ends of which have inwardly-directed parts 26 bearing on the two conductors.

Title: Improvements in and relating to speed indicators and recorders
IPC: G01P11/00
Filed: 1949-08-18
Abstract: 665,669. Electric speed measuring apparatus. EVERETT, EDGCUMBE & CO., Ltd., and AXWORTHY, F. R. July 4, 1950. [Aug. 18, 1949] No. 21537/49. Class 40 (i). In a speed indicating or recording device which measures the time taken to traverse a given distance, the moving body e.g. a train actuating electric switches at the respective ends of the measured distance, closure of the first switch starts a constant speed motor adapted to insert resistance at a constant rate into a circuit including the measuring instrument,. the second switch when closed stopping the motor and energising the measuring circuit to produce the speed indication. As shown, closure of the first switch S1 by the moving body energises a relay R1 which locks independently of S1, and energizes a D.C./A.C. converter F, which over contacts R14, R25 energizes the winding B of a synchronous motor C to drive the arm of a variable resistor D from a normal position X towards Y, and at the same time closes a locking circuit for F over X1. When the second switch S2 is closed by the moving body, relay R2 operates and locks. It releases R1 opens the motor circuit at R25, and at R22 applies potential from the transformer G to the series connected speed indicator K and recorder M which measure the rectified current flow through the resistor D. A variable resistor E is preset according to the distance between S1 and S2. The transformer G saturates over the operative range to compensate for voltage and frequency fluctuations. Relay R2 is released after a predetermined time, by a thermal switch T, energised over R23, whereupon the motor drives the resistor D back to its normal position. If the speed of the moving body is too slow to actuate S2 before the rheostat arm has reached point Y, no indication is given and the motor is automatically reversed to reset the apparatus. In a modification the switch S1 when actuated starts two timing motors each driving opposite members of a differential gear at the same rate. The second switch stops one of the motors whereupon the other motor drives the planet member until a fixed period has elapsed. The planet member drives the rheostat D, the resistance of which is decreased progressively and controls the speed indication as before. Alternatively, the rheostat may be wound to follow a reciprocal law. The voltage supply may be stabilized in any other way or the meter K fitted with an auxiliary coil to provide a control torque directly proportional to the supply voltage. The indication may be given remotely and an alarm, visible or audible, operated at excessive speed.
